expanding range for sort

[aupeter]

This is my first post and I am relatively new to Excel, so apologies if this is a mundane question;

I want to sort a Column, but when I agree to expand the range Excel only expands to four columns, not the eight available.

Anyone got any suggestions how I might expand the range to include the whole no. of columns.

Thanks

I think that's because there is an empty column between the 4th and the 5th column
